4.12.10
SPI
The MPX-S32G274A has 6 SPI and 4 LLCE SPI interf aces. Due to pin multiplexing
there are limitations.
Three SPI interf aces (and no LLCE SPIs) are available as primary interf aces on the
module connector.
SPI1 and SPI5 provide one chip select each, whereas SPI0 has two chip selects.
The SPI interf aces can also be conf igured as GPIO.
The pins are listed in the Appendix in chapter 10.4 and 10.5.
4.12.11
UART
The UART of the MPX-S32G274A module is used as debug console. It provides
TTL levels and needs to be converted to RS-232 or USB on the carrier, f or
example.
The pins are listed in the Appendix in chapter 10.4 and 10.5.
See chapter 4.12.12 f or the LINFlexD controller which also supports UART mode.
4.12.12
LIN
The MPX-S32G274A has 3 LINFlex controllers which can be either conf igured f or
LIN or UART mode. Moreover, there are 4 LLCE LIN interf aces routed as primary
interf aces to the module connector.
The LINFlexD
controllers’ pins are not available as primary interfaces on the
connector but shared with other interf aces due to pin multiplexing.
The pins are listed in the Appendix in chapter 10.4 and 10.5.
4.12.13
FlexRay
The MPX-S32G274A has 1 LLCE FlexRay interf ace with dual channels as primary
interf ace and another shared FlexRay interf ace due to pin multiplexing.
The pins are listed in the Appendix in chapter 10.4 and 10.5.
